With many databases in a system they are rarely independent from each other, instead pieces of the same data are stored in many of them. Using transactions to keep everything in sync is a fragile solution. Working with a stream of changes in the order they are created is a much simpler and more resilient solution, Martin Kleppmann stated in his presentation at the recent QCon London conference.
QCon New York planning is in full swing. QCon New York, the international software developer conference that attracts senior technical team members looking for innovator topics like immutable infrastructure, Lamba architectures, and innovations in DevOps, returns to the New York Marriott at the Brooklyn Bridge June 13-15th.
QCon New York returns to the New York Marriott at the Brooklyn Bridge June 13-15th. Check out this year's tracks.
Architecting a scalable and dynamic system without caching is explained by Peter Morgan, head of engineering for the sports betting company William Hill. The values of the bets on sporting events change constantly. No data can be cached; all system values must be current. Distributed Erlang processes model domain objects which instantly recalculate system values based on data streams from Kafka.
Some of this year’s confirmed QCon London sessions include: Survival to Ubiquity: Netflix Global Architecture by Josh Evans; Spring Framework 5 - Preview & Roadmap by Juergen Hoeller; The quest for low-latency with concurrent Java by Martin Thompson.
The 5th Annual QCon New York, a practitioner-driven conference designed for software architects/tech leads/leaders who influence innovation in their teams, has opened registrations. QCon New York will be held at the Brooklyn Bridge Marriott and has tickets on sale for $1645 through Dec 19th.
QCon London 2016 returns to the Queen Elizabeth II Conference center on March 7-9, 2016. While the influence of Silicon Valley is heavily present at all QCons, each conference features topics relevant to the local area. In addition to tracks like Back to Java, Architectures You’ve Always Wondered About & Containers (in Production), QCon London features tracks such as Disrupting Finance.
QCon San Francisco, a practitioner-driven conference designed for people influencing innovation in their software development teams, is fast approaching, and, with are so many new things, it’s hard to know what to report. With just 18 days until the start of the conference, QCON organisers are busy making final preparations to deliver yet more new innovations to 2015.
New this year to QCon London is an extra concurrent track (each day) for 2016. That means three new tracks to bring the total track (or conference themes) number up to 18. More tracks means more content to pick from. Here are QCon London’s 2016 tracks.

At QCon San Francisco, we offer two days of workshops (Nov 19-20). Workshops focus on developing the technical skills that leverage technologies you heard about from our expert practitioners during the conference sessions. Here is a glimpse at some of the experts you can learn from QCon SF ‘15 workshops.
Track topics for QCon San Francisco 2015 have been finalized and published to the conference website. Registrations for the event - which has been completely sold out for the past four years - are up 200% compared to the same time last year.
At QCon New York 2015, Mitchell Hashimoto discussed how tools such as a HashiCorp’s Terraform and Consul could be utilised to orchestrate infrastructure provisioning and application lifecycle management of cloud and container-based applications, with the ultimate goal of safely delivering software systems at scale.
At QCon New York 2015, David Fullerton presented a deep-dive into the monolithic C# / MS SQL architecture that powers the Stack Overflow website, which handles over 4 billion requests per month. Fullerton argued that by focusing on performance, scalability was included ‘almost for free’; and that by minimising the number of external application services, the need to pay ‘SOA tax’ has been avoided.
